The answer is b because 2S + L is equal to L + 2S.
It’s C. The slope needs to be the same. -5 makes it go down 5, right 1, and 5 makes it go up 5, right 1.
Answer:
See answers below
Step-by-step explanation:
Using the sin rule
a/sinA = b/sinB = c/sinC
a) x/sin110 = 16/sin27
xsin27 = 16sin110
xsin27 = 15.035
x = 15.035/sin27
x = 33.1
2) Using the cosine rule;
x² = 30²+14²-2(30)(14)cos125
x² = 900 + 169 - 840cos125
x² = 1069 - 840(-0.5735)
x² = 1069 +481.80
x² = 1,550.80
x =39.4
3) 28² = 18²+12²-2(18)(12)cosx
784 = 324 + 144- 432cosx
784 - 468 = - 432cosx
316 = - 432cosx
Cos x = -316/432
x = - 42.99
x = 180 - 42.99
x = 137.0 degrees
4) Using the sine rule
20/sinx = 33/sin91
33sinx = 20sin91
sinx = 20sin91/33
sinx = 19.997/33
sinx = 0.6059
x = arcsin(0.6059)
x = 37.3degrees
If descending means from highest to lowest numbers, then 14, 1, 1/3, 1/12
